Calculate the energy that 1.5 kg of mass contains
Vsevolod [243]

Answer:

4.5(10)^8 joules

Explanation:

Mass–energy equivalence is the principle that says that anything that has mass has an equivalent amount of energy. Converse is also true.

The relation between energy and mass is given by E=mc^2

Here, E denotes energy, m denotes mass and c denotes speed of light

Mass (m)=1.5\,\,kg

Speed of light (c) = 3 × 10^8 m/s

Therefore,

E=1.5(3)(10)^8=4.5(10)^8  joules.

The S.I. unit of energy is joules which is equal to 1\,\,kg\,\,m^2/s^2

Which of the following affects the rate constant of a reaction?
Dennis_Churaev [7]
Arrhenius' equation relates the dependence of rate constant of a chemical reaction to the temperature. The equation below is the Arrhenius equation
k = Ae ^{{ \frac{-Ea}{RT} } } where k is the rate constant, T is the absolute temperature. As the temperature of the system increases, the rate constant also increases and vice versa.
